Diesel fuel Filter/Water Separator
 

Opinions on the Stanadyne FM10 with an inspection bowl and water drain. Would this cause increased wear on the lift pump?

It filters to 5 micorns, so the main filter should live a long time.

If you skip the see-through bowl, you can install the FM 10 for around $40. I have one (FM 10) on its way for my '82 300D.

Where did u get that FM-10 filter, will it be good for wvo?

All i want is a better filter to keep my oem metal can filter from clogging because thats my main issue right now.

I've seen fuel filters with clear bowls similar in West Marine for $60 to $90 range.
Probably common in marine applications.

The FM 10 will likely clog faster than the original secondary filter. And costs more to replace. The main advantage of the FM 10 is that it also serves as a water separator.

You should be able to find a Stanadyne dealer in the Bay Area.

Around $120 for the filter and installation kit, including hardware, hoses clamps, etc.

thanks! ill look up stanadyne.

The beauty of filters like these is that you can easily drain the krud out of it without the need to replace the filter element every time.

I use a Racor in my 240D, basically similar to the Stanadyne model. I don't know about WVO though. I think a 5 or 1o micron filter might plug pretty fast. With the Racor, you can select from 2 or 3 different filter elements.

I'd prefer to use a water separator from an isuzu NPR. It works very well since it does not filter fuel, just separates. The only down side is the $140 price from GMC dealers.

Why do I need one? Is it absolutely necessary? Will it really make my engine/IP last longer? Seems that Kent guy is a really good scare tactician with his descriptions. My opinion is it's a nice 'feel good' upgrade however not absolutely necessary, because if it were, you guessed it, it would have come factory-installed. Just my .02

I gotta agree with sense on Kent (and his PITA, condecending daughter..)
I bought a Sunrooof repair kit and manual from him & when I called to ask for help his daughter had no idea and said Kent would be too busy to return a phone call. He never responded to my calls or to any emails . Yeah I'll be back to him REAL sooon.

Makes sense that it would've been factory installed.
and $120 is way high. Like I said WEst Marine has nice filters for 70- 90 $$ range.
But for dispersing my water worries I will always depend on Startron diesel additive....

I suggest you filter your WVO before putting in the tank. If you main filter is clogging, a 5 micron unit will clog faster.

I agree with Old300, if you filter to a finer degree before you put the oil in the tank, and at a cooler temperature than your oil runs in the car you should not plug filters.

No reason to replace the stock filter with this one unless your diesel tank is full of muddy water. You can but allot of replacement stock filters for $120.

Have used the Racor 230R with a 2 micron filter for many years to prevent dirt and water from reaching the IP. It has a vacuum gauge for visual monitoring of the element condition and tells me when the filter should be changed.

It is obviously not absolutely necessary. But a significant number of diesel vehicles do come with factory installed water separators. And since I don't have a lot of control over the quality of the fuel that goes in my tank, I think that $40 is a good value for the insurance that the FM 10 (or similar filter) will provide.
But I will be interested to see if I ever get any water out of the sump. Maybe it is a "feel good" upgrade. But I would rather have it and not need it than need it and not have it.
